What Is "Food Waste"?

 I'm a bit skeptical of the commonly used statistic that we waste x percent of the food we grow/produce (where x usually is 30 or more).

I'm not sure of the units of measurement--is it calories, volume, weight? It makes a difference.

And what is counted--if considering volume or weight, do you include the skins of bananas or the rinds of citrus?

And what is "waste"? Is corn grown for ethanol wasted?  Are animal parts used for pet food wasted?  

Produce Waste

The PBS Newshour is showing a piece on food waste, featuring an effort in California. It is part of a weeklong effort.  This particular one is laudable, featuring coordinators and software packages. 

But my contrarian side is present whenever I hear an estimate of "pounds of food wasted".  Looking at the produce shown, the pounds wasted include peach pits, watermelon rinds, etc.  I know measuring the "waste" is hard, and maybe there is a benefit to using fuzzy statistics: they stir up activism.  My instinct, however, is that better stats, more solid stats, are the way you build the base for a social movement, for changing norms. 

Simple Rules of Food Waste

As a retiree I hit the supermarket at odd hours, including times when employees or suppliers are changing the merchandise for sale.  The produce people go through the old produce and usually throw out the majority of it.  The bread people check the codes on the loaves and take back a lot.

We humans have a simple rule for food: when there's a choice, take the freshest and the best looking.  That simple rule means we waste a lot, because the whole marketsystem is founded on giving the consumer choices.

How Food Waste Happens

Watching DC's channel Four News.  (4 pm, 7/12/2020)Just had a consumer segment reporting on a test of having a supermarket deliver produce.  Bottom line, not good.  Berries mush, apples bruised, avocado not organic.

Agreement by the anchors that picking produce was personal, so such problems were big issues.

The program had no discussion of food waste, but it revealed why food waste happens--we pick the best out of the bin, and leave the worst, meaning the worst get tossed.

Chicken Bones Are "Food Waste"?

A discussion by Caitlin Dewey at the Post on why Americans don't eat left-overs any more.  This bothers the food movement, as embodied in the NRDC, who dug through our garbage and analyzed the results.  As someone who is the designated left-over eater for the household it bothers me. 

But--consider this: "The average person wasted 3.5 pounds of food per week. Of that, only a third consisted of inedible parts, such as chicken bones or banana peels."

Do the foodies really want me to eat my banana peels and chicken bones?  Seems they're cheating on their stats--including inedible waste boosts their headline figure of how much we waste.  Shame.

The analysis goes on to say: 

"... many consumers appear to stash Tupperware containers in their fridge and then forget to excavate them before the food goes bad. Other times, consumers grow bored of eating the same food on multiple occasions.“There were two big reasons people threw out edible food,” Gunders said. “They thought it had spoiled, or they just didn’t like leftovers.”

We've done that, but we should blame our huge refrigerators (in huge houses--have you ever noticed the refrigerators in the kitchens of British houses in their murder mysteries--usually the size of the fridges for college dorm rooms these days) and Tupperware.  :-)
